DUMPING DEVICE FOR WAGONS.

SEEGIEIGATION forming part of Letters Patent N 0. 677,971, dated July 9, 1901.

Application filed February 20, 1900. Renewed January 24, 1901. Serial No. 44,543. (llo model.)

To all whom it may concern.-

Be it known that I, HENRY FOX, a citizen of the United States, residing at Bay City, in the county of Bay and State oflvlichigan, have invented certain new and useful Improvements in Dumping Devices for Wagons; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention pertains to clumping-wagons; and the improvement consists in certain means whereby the objects of my invention are accomplished. These objects are, first, to produce a device whereby the contents of a Wagon-box may be easily and quickly dumped without the labor necessary to elevate'part of the load before it is dumped, as is the case with some common forms of wagonboxes; second, to provide for such purpose a dumping device that can be applied to existing formsof wagon-trucks and will be adapted for use with ordinary forms of wagon-boxes, and, third, to so construct a longitudinallysliding frame to receive the wagon-box that lateral movement of the box is prevented and the longitudinal movement by which the box is dumped is kept under the control of the operator while dumping the load. The means I employ to accomplish these objects is illustrated in the accompanying drawings throughout the several views, of which similar characters of reference designate corresponding parts and devices.

Figure 1 is a top View of the device. Fig. 2 is a longitudinal section on the line a: a: of Fig. 1. Fig. 3 is an enlarged transverse section on the line y y of Fig. 1. Fig. 4 is a side view of the device applied to a wagon, showing the box in position for dumping the load.

As is clearly shown in the drawings, the device consists in a lower frame 1, of rectangular form and of suitable size to rest between the stakes of a wagon-truck, and an upper frame 2, resting upon the lower frame and adapted to move longitudinally along it. The longitudinal members of the lower frame are provided with flanges 1, that prevent the upper frame 2 from becoming displacedlaterally either in transit or while unloading. Rollers 3, carried by the longitudinal members of the frame 1 and having their upper surfaces projecting slightly above the surface, serve as a bearing, along which the upper frame may be slid longitudinally. The lower surface of the frame 2, that comes into contact with the rollers, is preferably protected by a strip of metal secured thereto, as at 4, Fig. 3. The rear end of the side members in frame 1 are rounded,

as at 5, Figl 2, in such manner that the upper or otherwise, I provide transverse shafts 9v and 9*, carried by the lower frame and adapted to wind up the flexible rope or chains 10 and 10, which are attached to the ends of the up per frame 2. The shafts are rotated by means of a suitable crank, and a ratchet-wheel 11 and pawl ll are preferably secured to the shafts to prevent their movement when the load is in transit. Winding up the chain 10 on the shaft 9 draws the frame 2 and the box attached to it backward until it becomes overbalanced, tips downward, and dumps its load from the rear end of the wagon-box through a door, as shown inFig. 4, or in other suitable manner. If the load is to be dumped through an opening, as through the trap-doors of a sugar-beet-storing shed, the entire load is at once discharged; but if the load is dumped on a'level floor the wagon may-be moved forward a few feet to discharge the remaining part, the wheels 8 preventing injury to the end of the upper frame. After unloading the upper frame is drawn back on the lower frame by means of the shaft 9 and its chain or cord 10 The pawl and ratchet preventfurther movement of the 'upper frame, as above described.

It is thus seen that I produce an attachment that can be at small expense applied to existing forms of Wagons to convert them into dumping-wagons Without altering either the construction of the wagon-box or the runnin ggear.

What I claim is 1. In combination with a dumping device of the kind described, a rotatable shaft secured to the frame near its forward end; a flexible cord one end of Which is secured to said shaft and the other end secured to the rear end of the box; a second shaft rotatably mounted near the rear end of the wagonframe; a flexible cord secured at one end to the second shaft and leading direct to the front end of the box to which the other end of the cord is attached, the intermediate portion of this cord being suspended freely be tween the shaft and the front end of the Wagon-box when the latter is in its lowered or dumped position, substantially as described.

2. In combination with a dumping device In testimony whereof I aflix my signature 30 in presence of two witnesses.
